 sound of a gigantic rattle, or of the syllables ' chacarata, cha- 

 carata,' from which they get their Guarani name, 'Charata.' 

 All the birds in one part of the forest uniting in this, the effect 

 is almost deafening. Other companies of birds answer, and 

 on a fine morning in the Chaco, just after sunrise, one hears 

 these Charata-choruses resounding in all directions.

 who attract it by imitating the call-note, and shoot it with 

 bow and arrow. Amongst the Tobas it is called " Cochine," 

 in imitation of its call."
